To program an extra key yourself you need at least one key that is already programmed, otherwise you will need to have a Dealer do this for you.

1. Insert the programmed key into the ignition and turn to run (not start) wait until the security light goes out
2. Quickly remove the first key and insert the new (unprogrammed and cut) key and turn the ignition to run (not start). Again waiting until the security light goes out.
3. Turn the ignition to off and removed the newly programmed key
4. Then reinserted the newly programmed key and turn the ignition to start.
